Need to solve for Y by filling in the blanks<br>(y +44)°, 86, (3y)°​
lapo4ka [179]
Answer:

1.89

Solution:

We have -44x - 86 = -3

First, we move the non x terms to the RHS of the equation. To do this, we add 86 to both sides.

Note: if a = b, then a + c = b + c
Therefore, -44x - 86 + 86 = -3 + 86

or, -44x = 83

Next, divide both sides by -44, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c
-44x
-44
=
83
-44

or, x = -1.89


Explaination:

This is right I guess

Pls help! <br> Identify the range of the function shown in the graph. <br><br> Thanks
s2008m [1.1K]

Answer:

A

Step-by-step explanation:

Range is all y values of a graph and seeing that it has no arrows means its not infinite so its not B. The graph starts at 0 and ends at 5 so the smallest value is 0 and the largest is 5 therefore making the answer A.

Answer:

It will take them 18 hours.

Step-by-step explanation:

To find the answer of this, you must first multiply the amount of people by the time:

6 * 15 = 90

Then to find the time it takes 5 workers, divide this by 5:

90 ÷ 5 = 18

So it will take them 18 hours!
